It's actually the best thing to use an ASIC tightly coupled with DRAM for - for example, HBM and HBM2 which reduce latency and increase throughput by placing the DRAM on an interposer with the ASIC die, or even putting the logic on the DRAM die itself. It would need at least proof that existing chips using HBM are ideal for Cuckoo Cycle (unlikely) and that no DRAM manufacturer could ever be coaxed into making an ASIC (even harder to guarantee). I think any long term PoW change is irrelevant to the review or adoption of the covert ASICBOOST BIPs, given the many unresolved problems of such a change. _______________________________________________ bitcoin-dev mailing list bitcoin-dev@lists.linuxfoundation.org https://lists.linuxfoundation.org/mailman/listinfo/bitcoin-dev
